The Path of Biomass Energy Conversion: From Dawn to the Future - December 1999 to January 2025

The Path of Biomass Energy Conversion: From Dawn to the Future - December 1999 to January 2025

1990s: The Era of Emergence In the 1990s, high-efficiency biomass energy conversion technologies began to gain attention as a key to sustainable energy supply. Research progressed particularly on power generation technologies utilizing waste-derived biomass, seeking to improve the efficiency of gasification and pyrolysis technologies. However, due to technical constraints and cost issues, commercialization was not achieved, leaving challenges such as improving combustion efficiency and securing a stable biomass supply.

2000s: Technological Innovation and Demonstration Entering the 2000s, power generation using biomass gasification technology gained attention. In Japan, Chugai Ro Kogyo Co., Ltd. advanced the development of a gasification power generation system utilizing woody biomass and established a demonstration test facility in Yamaguchi City, Yamaguchi Prefecture. In Europe, biomass power plants began operation in Germany and Sweden, but challenges with fuel supply costs and conversion efficiency prevented large-scale adoption.

2010s: Progress Toward Practical Application The 2010s saw advances in the practical application of biofuels. IHI Corporation promoted research into biofuels utilizing algae, aiming for practical application as aviation fuel. In the United States, commercial production of bioethanol from cellulosic biomass began in earnest, with adoption progressing in states like California. However, challenges such as price competition with fossil fuels and ensuring a stable supply of biomass resources persisted, making government support policies crucial. 2020s: New Horizons Entering the 2020s, high-efficiency conversion technologies for biomass energy achieved further advancements. In thermochemical conversion technology, techniques for gasifying biomass at high temperatures to produce synthesis gas improved, and the production of biomass-to-liquid (BTL) fuels via Fischer-Tropsch (FT) synthesis advanced. In biochemical conversion technology, the saccharification and fermentation of cellul
osic biomass evolved, improving the production efficiency of bioethanol.

Corporate initiatives are also becoming more active. Mizui Engineering Co., Ltd. has been developing biomethane technology and was selected for NEDO's Green Innovation Fund project. Mitsubishi Heavy Industries, Ltd. continues to develop biomass gasification power generation systems, aiming for high-efficiency energy conversion. However, challenges remain, such as cost reduction, supply chain development, and environmental impact assessment, requiring further policy support and technological innovation. Going forward, the realization of sustainable biomass energy use is expected through public-private partnerships and international cooperation.
